HEATER FOR RADIATORS.

Specification of Letters Patent.

Patented Aug. 7, 1917.'

Application filed January 15, 1917. Serial No. 142,554.

Be it knownthat we, WILLIAM K. MASON and CHRIS L. DoNoIIo,4 citizens of the United States, residing at Cambridge, `In the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Heaters for Radiators, of which the following is a specification.

This invention relates chiefiy to radiators for household use, and has for its object to enable an ordinary radiator such as is commonly heated by .steam or hot water, to be utilized as apart of a complete heating apparatus, preferably portable, the apparatus as a whole includ-ing an ordinary radiator, a boilery locatedbelow the base portion 'of the radiator and connected with said base portion by flow and return conduits` means supporting said boiler.A spaced above a floor, and a burner located under-the boiler and arranged yto direct its fiame against the underside of the boiler, said base portion, the ilow land return conduits; and the boiler constituting a Water-circulating system adapted to supply vapor to the radiator.

. Of the accompanying drawings forming a part of this specification,'-

FigureJ lis a sidev elevation of a 'hea-ting apparatus embodying our invention.

Fig. 2 is an end elevation of the same.

Fig. 3 is a. section on line 3-3 of Fig'. 2.

Fig. 4 is a plan view of the boiler.

Fig. 5 is a section on line 5 -5 of Fig. 4.

The same reference characters indicate the same or similar parts in all of the figures.

In the drawings, 12 represents a common type ofsteam or hot water radiator eemposed of a plurality4 of upright sections connected alt their llower ends tofornr a water- 4o,

containing base portion 12, and at their upperends to permitthe passage of steam or vapor: from section to section.

The 'bjase portion of the radiator presents heat-radiating surfaces of relatively small area, and the upper portion formed b.y the said vsections presents heat-radiatingsurfaces ofrelatiively large area. ThebaseportibnlQ means at its end portions is provided with the usual legs 13 with for 'engagement with a. flow conduit 15,'*and av return conduit" 14 which communicate with `the base 12l at i points -bove the bottom of the latter, soi 'that a relatively shallow accumulationof water fay bemaintaned inthe baseportion,r as'shown byvFig. 3. The said fiow and return conduitsgso far asl their relation Iinafter explained. gated boiler having top and bottom sides4 of considerably greater area than its ver-` tical edges, so that the boiler is ada ted' il. COIICRVG deiiected radially' .togthe radiator is concerned, are the same as 1n the ordinary steam or hot Water heating apparatus. The conducting capacity of thefiow conduit 15 is greater than that of the return conduit, for

16 represents an elonto lrold and conduct a relativel i sha l'ow bod y i side of the boiler preferably resenting the outline shown by Fig. 4. he end portions of the reservoir' are connected with the conduits 14. and 15, the boiler being coupled to and spaced from the base por; tion 12a of the radiator by said conduits, as shown by Figs. 1, 2 and 3.

The boiler and radiator are supported at a sufficient height above the Hoor to permit under the boiler, of a burner the location,

17, which is preferably a blue flame oil a purpose here-- ,y or4 accumulation of water, the top i burner, which may be carried and Varded by the supporting means, hereina r described and is arranged to direct its flame against the under side of the boiler. Pref- I erably',vthe said under side is provided with portion 16,* against which the burner flame impinges and by which it ,is and somewhat .`down- Wardly.

.1`he said supportingmeans may include a suitable curb .19, forming the' upright Walls'A of a heat-confining casing around the burner lfd antd provided withan opening in one si e o permit access .to the burner, said openingbeing covered by #movable d'or'nQO.` 1

The base portion 12 of the radiatorand the boiler 16 are charged witl'rwater.-asindicatedby. Fig. 3, therebeing preferably' only suiiicient water in the bese portion 12 to cause the circulation hereinafter de'- generatedby A scribed. The effecty of -the heat the burner is to heatthe water and ceu circulation thereof, as indicated by farro caused, by thev difference` ducting capacitiesof the conduits to flow in one direction in the boi thc'fiow conduit'` lgund toflow inV the o site direction-inthe-.lbase portionof thiiuxla"l and continuously give# of""vap'ior,I

diator, I which fills the'ulpper4 portion of tHe-radiator above the ibase 12' cornes active. 'l

The boiler is preferably r'pianetiwat wsI y Jing@ .Fig 3. The water heated in' the lboiler; is betweenthy manA mii n 1 cover for the curb 19, adapted to interceptI Y any smoke which may be causedby imper- :feet combustion when the burner is first lighted, and prevent the smoke from soiling the radiator. The said cover and curb constitute a casing adapted to confine flames and heat under the reservoir, so that therey is no danger ot igniting dress skirts, etc., vwhich may be near the structure. Said casing also stabilizes the flame by preventing air currents from impinging hm-izontally upon it. The radiator legs rest on the flanges 24, as shown by Figs. l and The casing 19 is preferably provided with a bottom 25 having an opening 26 to admit air upwardly to support combustion. The ends of the casi-ng' may be provided with outlets 27 for hot air 'and products of combustion, these being preferably located u'nderthe projecting end portions 16b of the boiler. The oil resen'oir, ,the burner, and the oil-conducting means connecting said parts, may be constructed and arranged in any suitable way, the structure, including said parts, here represented somewhat conventionally, being well known in blue flame oil stoves, said structure being provided with means, including a. stern 28, for regulating the flow of oil. It is obvious that the radiator may be entirely lilled with water, if desired, although we do not recg ommend'this. We find it preferable to maintain the water level below the top of the base portion, substantially as indicated b. Fig. 3, so that vapor is free to rise from all, portions of the surface of the moving body` of water.

e do not limit ourselves to an oilfburner and may use a burner forgas or other suitable fuel. i, f '.We have found that the above-described heating apparatus isxboth eflicient and eco-r nomical. The entire apparatus' vas illustrated, constitutes a self-contained heat-gcnerating,l andradiating structure ada ted to be'.V transported from place to place, t e' sup- -p'o1"ting,="` means being preferably .provided with casters 22. An oil reservoir 23 may beY so connected with the structure as indicated by Fig. 2 to supply oil to tlierbvux-'nc'l".v now be seen that the boiler, the

It will flow' and return conduits, and-theA radiator, constitute a water-circulating and heat-radiating s tructureadapted to contain a limited'ichargie of .waterwhich fills the boilerand the 4said ,cnduits, and only partly fills the base portion ofz the radiator, the levelof said chage bei-ng maintained at a' predeterminedlieightv and below the vapor-receiving portion of the radiator, because the dey liveihlifgl endof. theffiow conduit and the in' take eiriynattirexret'urn'condut are at substantiallyfthcsame elevation at their pointsof connection with the radiator. The delivering end of the return conduit and the f,

,pacitics of the flow 'and return conduits causes a continuous flow of the charge of water in one direction through the boiler to rcceive'hcat, and in the opposite direction through the base portion of the radiator to continuously give oft' vapor to the` Vapor-receiving portion of the radiator'.

It will also beA seenv that thecurb 19' constitutes the base ofa self-contained` portable structure, and that the boiler 16, the radiaY tor, and the conduits 14 and 15, constitute a superstructure which is applicable as a single part to said base,` the radiator being rigidly connected with the'boiler by said conduits, and the radiator legs 13 being held by the conduits firmly seated on the portions ofthe boiler formed by the flanges 24:. The parts'of said superstructure may be conveniently assembled before the application of the superstructure to the base. Theiassem blage of the base and superstructure forms a substantially closed casing whereof the boiler is ,the top, said casing guarding the burner flame.

We claim 1. In aportable heat generator and radiator the combination of an elongated boiler,

flow and return conduits extending .from opposite ends of the boiler, a. radiator coupled to the boiler by said conduits and haviug an elongated water-containing base portionsubstantially parallel with ythe boiler, and a vapor-containing upper portion, ,a base supporting the boiler and radiator in substantially horizontal positions, and a burner in said base arranged to tdirect its flame against the bottom of the boiler, the

delivering end of the flow conduit and the` intake end of the return conduit bein at substantially the same elevation 'at t cir ypoints of connection 'with the radiator, andl arranged to maintain the level of a charge of water, 'filling said boiler vand conduits, at

a predetermined level below said vapor-containing portion,` the delivering end of the return conduit andthe intake end'of the ow conduit being at substantially the same elevation at their points of connection. with the boiler, and the conductingr capacity of onel conduit being greater-than that of the other, whereby, when the boiler is heated, said charge is caused to flow in one direction through the boiler and receive heat, and in the opposite direction throught-he base portion of the radiator and give off vapor. I'

2. A portable heat-generating-andradiat ing structure comprising a curb havingan open top and constituting the base portlon of the structure, a burner Withln the curb,

and a superstructure applicable as a single part to the curb and composed of a boiler formed to cover thevuppr end of the curb,

a radiator above the boi1er,'and flow and. return conduits of dierent capacities connecting opposite end portions of'the boiler with opposite end portions of 'the radiator.

3. A portable heat-generating-and-radiating structure comprlsing a curb having an open top and constituting `the base portion oijshe structure, a burner Within the curb, and a superstructure applicable as a ,sin le part to the curb and composed of a boi er formed tocover the upper end of the curb, a radiator above the boiler, the flow and return conduits of different capacities connecting opposite endportions of the boiler with opposite end portions of the radiator, the

,radiator-being provided with downwardly -nectingopposite end portions of the boiler withA opposite end portions of the radiator, the boiler being);y provided with flanges at its lower portion, and the radiator being provided with downwardly projecting legs which are conned by said conduits against said flanges.

In testimony whereof We have affixed our signatures.
